I'm thinking to use the clay balls to enrich my gravel substrate. I don't have any other substrate below the gravel (I received the aquarium from another person already running and cycled).
I have 3 questions regarding the clay balls:
- If I place on clay ball per plant in the gravel (so if i have 20 planted plants I would need 20 balls placed inside the gravel) is that as "real substrate" ?If not as good, is it a convenient alternative, which can avoid me inserting a "real substrate" in the aquarium ?
- In DRAK site, it is said not to place more than 3 or 4 clay balls in a 100L aquarium, but how do I do that id I have 20 plants in a 100 L aquarium ?
- After 6 months what do I do with the balls that are inside the aquarium ? Should I leave them there, and just add new balls,m or should try to remove the old balls, and in this last case how to do it, once the clay after 6 months should be very soft and not easy to take out.
Thanks and best regards
